It's been so hard, lately to keep up with all that's going on with PWG!
Plus a REAL job!! We're all in this boat (including YOU!) and I suspect
this has more to do with the (quiet) response than lack of interest.

Nonetheless, I agree... it's work you can't (and shouldn't) afford to
do if there's not a good chance that PWG members will make use of it.

Let me get this straight. A STEP.1 publisher would not need to implement
the SENSE message format. Just the Text Event Protocol itself and this
is designed to work with standard networking protocols. Right?

Can I ask, how would a STEP.1 publisher communicate with a SENSE server?
Could it be via a telnet session? Is there a preferred method?

I would be willing to do this in a couple weeks after a major deadline
of mine passes. I'm a bit reluctant, because it seems every time we
try to define a practical set of (anything) what should be a few tweaks
turns into a free-for-all and, before you know it, we've made an
unscalable mountain of a (very useful) mole hill.

Sorry, it's late... and I'm feeling rough around the edges. This is not
aimed at anyone in particular, in fact the readers are probably thinking
I should take a look in the mirror (WHEREs that hrPrtDetectedErrorState
2nd Octet proposal... Harry?).

If I were to start with JMP events... it would look like this

JobEvent (Job Index; Time stamp)
Started
Completed (bin x)
PageCompleted (page n)
CopyCompleted (copy i)
Alarm (type)
Jam
Canceled (which means canceled, aborted, terminated etc)
Paused

I would stipulate that periodicity on PageCompleted is adjustable via
SNMP set or vendor specific (every page, every 3 pages, every 5
seconds no matter what page it catches etc.).

I'm sure we could find a few more good ones, but, like your current
STEP.1 proposal, a brief list like this could go a long way to
facilitating job management.
